In an arrangement for detecting flaws in ware e.g. glass bottles, the ware is rotated, and urged whilst rotating towards and against a reference surface whereat it is inspected, the plane being substantially normal to the axis of rotation. Glassware fed by a belt (12) Fig. 1 (not shown) and between guides (66), (67) Figs. 4 and 9 (not shown) is carried around a semicircular track defined by guides (52), (53) around which it is inspected for defects by a number of adjustably mounted photo-cells (80). The tests are carried out at various positions with the article being rotated as it is lifted from the belt and held at predetermined heights against reference surfaces. A defect indication at one of the test positions energizes a solenoid corresponding to that position (93-95) Fig. 7 (not shown) to position a rod (92) corresponding to the article, in the edge surface of a rotating disc (90) the pins actuating microswitches (98), (99) in a reject circuit to separate faulty articles as they approach the delivery point. The test apparatus which is suspended from above the conveyer belt may be adjusted in height and includes an air motor for rotating a disc guide head (31) which moves the articles around the track, and a second motor for rotating a second disc (33) for rotating the articles and in conjunction with canted rollers (44), (45) lifting them into contact with reference surface (63). The bottles are on arrival, cradled between a pair of rollers mounted in and outwardly biased from, disc (31) and pressed against the guide rails which include rollers at intervals. An alternative guide head arrangement in which cradles are fixed in disc (31) and eject levers are operated by a fixed central cam is described with reference to Figs. 9-11 (not shown). The first air motor is switched on by the interruption of a light beam by the arrival of an article. Different parts of the article are checked in the different positions and alternatively the test may be by electrical or mechanical probes.

Abstract: 1,045,711. Magnetic storage devices. WESTERN ELECTRIC CO. Inc. April 11, 1963 [April 13, 1962], No. 14512/63. Heading H1T. [Also in Divisions G4 and HC] A data storage device comprises a card of magnetically insulating and optionally conductive material which carries an array of magnetic elements, the data represented by any row of elements being read out by energizing a selected word-read winding positioned adjacent the card and detecting the outputs induced in associated sense conductors, the word read windings and the sense conductors being affixed to a magnetic or non-magnetic board with each sense conductor crossing the word read windings adjacent to data storage positions on the card. In Fig. 1, word-read windings 12 1 -12 3  in the form of copper strips are displaced from the sense conductors 111- 114 by an angle of 45 degrees and are mounted on a board 10. At each winding intersection a low-coercive-force magnetic switching element 16 is provided on the adjacent card 15. Each switching element has a contiguous highcoercive-force storage element 17 in which storage of a " zero " is represented by a saturated remanent state in one sense and storage of a " one " is represented by the unmagnetized state. Alternatively, the " one " state may be represented by saturated remanent magnetization in the opposite state. Since the elements 16 are magnetized by unidirectional current in a winding 12 1 -12 3 , a sense conductor output is produced only if the associated element 17 stores a " one." Recorded data is charged by energizing magnetic heads (not shown) adjacent the various storage element 17. In a modification, Fig. 3 (not shown), the word-read windings and sense conductors are orthogonal and the low-coerciveforce switching elements have a preferred magnetization axis.
